SPECIFICATION formingpart of Letters Patent N 0. 678,061, dated July 9, 1901. Application filed September 6 1900} Serial No. 29,196. (No model.)

T0 on whom, it may concern-.-

citizen of the United States, residing at Colmar, in the county of McDonough and State of Illinois, have invented a new and useful Windmill-Regulator, of which the following is a specification.

This invention relates to windmill-regulators; and one of the principal objectsof the invention is to provide means for transmitting the motion from the pump-rod to the windmill connection and imparting a certain definite amount of throw to the windmill connection irrespective of the extent or amount of throw of the pump-rod, thus adapting the improved mechanism to be applied to and used in connection with different constructions of windmills in which difierent throws of the pump-rod are employed. By making the windmill-regulator capable of universal adj ustment in the manner above indicated the said regulator may be applied to any windmill and 1 The regulating mechanism is associated with and controlled by a float mounted within the reservoir or tank and suitably connectedby operating devices with the regulator.

It is also an object of the present invention to construct the windmill-regulatorin such a manner as to render it convertible from a cam-operated device to a straight-lever'operating device, which feature of convertibility may be taken advantage of when the governor or regulator is applied toa pumprod having a certain amount of throw.

Another object of the invention is to provide, in connection with the operating-cam, a

lever which is adjustably associated there-' j paw ls out of engagement with the draw-bar, Be it known that I, HERBERT K. TABLER, a

the pawls themselves being adapted, by reason of their form andarrangement, to assist in throwing the tripping devices and releasing the draw bar for the purpose of throwing thewindmill into operation.

With the above and other subordinate objects in View, the nature of which will more readily appear as the description proceeds, the invention consists in the novel construction, combination, and arrangement hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a portion of a windmilltower, illustrating a pump, pump-rod, tank, the windmill-regulator, the windmill connection, and the float operated connections which influence the windmill-regulator. Fig.

2 is an enlarged side elevation of the 'wind-.

mill-regulator. Fig. 3 is a similar view looking from the opposite side. Fig. 4 is a plan view of the same, showing the pump-rod and pump-rod link in section. Fig. 5 is a side elevation taken from the same side of the apparatus as Fig. 3 and showing the mechanism adjusted for converting the cam-operated device into a straight-lever connection between the pump-rod and draw-bar. Fig. 6 is a view similar to Fig. 1, showing the manner of mounting the windmill-regulator adjacent to the well-platform.

Similar numerals of reference designate corresponding parts in all figures of the draw- -1ngs.

' Referring particularly to Fig.1, 1 designates a pump of anyordinary construction, mounted at the base of a windmill-tower, having the usual upwardly-converging uprights 2, con- .nected at intervals'and suitable elevations by cross-beams 3.

4 represents the pump-rod, which extends from the piston-rod of the pump upwardto the crank wheel or disk of the windmill, so as to be operated thereby in the usual manper, and 5 denotes a tank or reservoir to receive the water as it is pumped by the windmill.

In order to throw the windmill-regulator into and out of operation and correspondingly affect the windmill, I employ a float 6, arranged in the tank 5 and having a connection 7, extending to a bell-crank 8, mounted upon a centrally arranged transverse supporting-beam 9, connected with. the windmilltower at a point preferably overhead and out of the reach of persons standing on the wellplatform, the said bell-crank being also connected by cord or wire 10 with one arm 11 of 9 and also provide grooved extensions form-.

ing guides 15 for a vertically-movable drawbar 16, the said draw bar being further steadied and guided by grooved guides 17 at the upper end of the upwardly-extending portion of the bracket or frame 13 at a suitable distance above the supporting-beam 9.

The draw-bar 16 is provided at its upper end with an opening 18 to receive the pullwire 19, which, together with the draw-bar 16, forms the windmill connection, to which rotation is adapted to be transmitted from the reciprocating pump-rod 4 by the mechanism to be described. The draw=bar 16 is of cruciform shape in cross-section or provided with two sets of oppositely-extending flanges, so as to secure strength and lightness, and the lower end thereof is provided with an opening to receive a stop-ring 20, which upon coming in contact with the guides 15 will prevent the further upward movement of the windmill connection. One of the flanges of the draw-bar is provided with saw-shaped ratchet-teeth 21, so that the draw-bar forms a rack-bar which is adapted to be engaged by an operating-pawl 22 and a holding pawl or detent 23, said pawls being arranged with the operating pawl or dog 22 above the holding pawl or detent 23.

The draw-bar-actuating mechanism comprises a cam-operating lever 24, one end of which is pivotally connected to a pump-rod link 25, hung upon the pivot 26 of a pivotplate 27, secured to the pump-rod 4. The opposite end portion of the lever 24 is adjustably fitted in a slotted opening 28 in a laterally-projecting lug or arm 29 on the hub or pivot sleeve 30 of a cam 31, the lever being connected adjustably with the cam by means of a headed pin 32, which is fitted through an opening in the lug or arm-28 and held by means of a cotter-pin or other suitable fastener 33, the said pin being adaptable to any of a longitudinal series of openings 34 in the lever 24, thus providing for lengthening or shortening the distance between the fulcrum of said lever and the point at which it connects the pump-rod link. I11 this way the amount of throw of the draw-bar may be primarily regulated with respect to the amount of throw of the pump-rod, so that a predeter mined number of throws of the pump-rod will depress the draw-bar sufficiently to throw the windmill out of operation.

The cam 31 is mounted upon a stud-shaft 35, connected with the bracket 13, and'as the cam is oscillated by the lever 24, as the latter is in turn vibrated by the pump-rod link carried by the pump-rod in its reciprocatory movement, said cam comes in contact with and operates against an an tifriction-roller 36, journaled upon a pin or stud 37, carried bya pawl-operating lever 38, which is fulcrumed at 39 on the frame or bracket 13, adjacent to the extremity of the upwardly-extending portion thereof. The roller 36 is connected to said lever on one side of the fulcrum 39, while connected with the lever at the opposite side of its fulcrum is a pawl carrier or hanger 40, to which the operating pawl or dog 22 is pivotally connected by means of a pin or pivot 41. The pawl-carrier 40 comprises a stop shoulder or flange 42, against which the pawl 22 is adapted to strike and normally hear when in operation, as shown in Fig. 3, so that the pawl proper cannot swing outward away from the draw-bar without moving the carrier 40 with it. The holding-pawl 23 is similar in form and arrangement to the operatingpawl and is connected with a carrier 43, having a shoulder or flange 44-for limiting the outward movement of the pawl relatively to its carrier. The carrier 43 is pivoted at 45 to an arm 46 of the frame or bracket and is extended abovesaid pivot or fulcrum, where it is provided at its upper extremity with a weight 47. This upwardly-extending arm of the carrier diverges or extends outward away from the draw-bar when the pawl carried thereby is in operative engagement with the draw-bar, as shown in Figs. 2 and 3. Each of the pawls 22 and 23 is provided with a tooth or shoulder 48 to engage the teeth 21 of the draw-bar, and each pawl is further provided with an outwardly-curving tailpiece 49,adapted under certain conditions to bear against the teeth 21 and prevent them from throwing the pawls upward with sufficient force to break or bend them. The operating-dog 22 is further provided with a laterally-projectin g stop-pin 50, adapted when the pawl is thrown upward to come in contact with the dog-operating link, hereinafter referred to, which will cause the pawl to drop back to its normal position.

The trip-lever 12 is fulcrumed on a pin or stud 51, and fulcruined upon the same pin or stud is a shipping-lever 52, said lever being pivotally mounted at a point intermediate its ends and having connected thereto at points equidistant from its fulcrum a pair of pawloperating links 53 and 54, the link 53 connecting pivotally with the pawl-carrier 40 and the link 54 connecting pivotally with the upper arm or extension of the pawl-carrier 43. By connecting the shipping-lever with the pawl-carriers in the manner shown and described when the upper end of the shippinglever is vibrated toward the draw-bar both the operating-pawl and the holding-pawl will be thrown out of engagement with the drawbar, and in order to insure and facilitate the IIO ere-,oer

tripping of the pawls the shipping-lever 52 is provided at its upper endwith a weight 55, having a stop surface or shoulder 56, adapted when the weight moves inward to come in contact with the stoppin 57 on the pawloperating lever 38, thus holding said lever elevated above the cam 31, which latter may then continue its oscillations without affecting the lever 38, and consequently without operating the dog 22. At the same time that the weighted end of the shipping-lever is thrown toward the draw-bar the weighted end 47 of the carrier 43 isthrown in the opposite direction and also toward the draw-bar, and the said weights are so arranged with respect to the fulcrums of said members that the weights will pass the vertical planes of the fulcrums, and thus remain in -a position of rest with the pawls inactive until the parts are again thrown into operation bythefloat risingin the tank and operating by means ofthe described connections on the trip-lever 12.

In orderto prevent the lever 38 from moving upward too far, a spring-stop 58 is secured to the upperportion of; theframe or bracket 13 and overlying-the lever ,38. In order to compensate for the slipping of the holding-pawl 23 past the teeth of the drawbar as the latter descends, the operating-link 54 is provided with a slot 59 to receive the pivot-pin 60, carried by the shipping-lever 52.

The trip-lever 12 is mounted on the same fulcrum as the shipping-lever, and said triplever is provided with several arms, one of which,'6l, carries a weight 62 to hold the same downward when the'regulating mechtachment of a hand connection 64, extending downward within reach of an operator standing on the well-platform, who is thereby enabled to swing the trip-lever and trip the mechanism before it is operated upon by the float within the water tank or reservoir. Opposite the arm 11 the trip-lever 12 is provided with another arm 65 for the. same purpose as the arm 11, butadapted to receive the connection 10 in case the tank and the, float should be arranged at the opposite side of the center of the windmill-tower, thereby enabling the float to operate with a pulling ac: tion on the trip-lever. .In order that the triplever 12 may throw the shipping lever, said trip-lever is provided with a laterally-extending log or shoulder 66, which'operates in conpawl-carriers'and pawls are moved into en-y 38, and moving the dog 22 up and down, causing said dog or pawl to successively engage the teeth of the draw-bar until said draw-bar is forced downward sufficiently to throw the windmill out of operation, the holding-pawl 23 serving to prevent the draw-bar from moving upward as the operating-pawl is ascend ing to take a fresh hold upon the draw-bar.-

As long as the tank remains filled the pawl 22 will continue to move up and down, butwill no longer affect the draw'bar, as it will move in contact with the smooth untoothed portion 67 of the draw-bar. As soon as the water begins to lower in the tank, however, and the float to descend the connections are drawn upon, with the result that the lever 12 will be rocked in the opposite direction, the weight-arm 61 moving upward, and the shoulder 66 serving to vibrate the shipping-lever in the same direction. Just as the, upper weighted end of the shipping-lever is moving toward the drawbar and relieving the tension against the pawls 22 and 23 the draw-bar l6 begins to move upward and bears in a corresponding direction against the shoulders or teeth 48 of the pawls, with the result that thepawls act through their pivotal connection with their carriers to thrust the carriers outward away from the toothed side of the draw bar, and in this way the pawls assist in tripping the mechanism and throwing the weights 47 and 55 toward each other and toward the draw-bar until finally the pawls are thrown entirely out of engagement with the drawbar, the latter being released and allowed-to move upward, thereby throwing the windmill into operation and allowing the pump to replenish the supply of water in the tank.

Where the regulator is to be coupled to a pump-rod having a short throw, the regulator may be converted into astraight-lever-operating device, dispensing with the cam and some and is turned end for end and bottom side up and applied as shown in Fig.- 5, the lever being bolted to the pawl-operating lever 38, as

shown in Fig. 5, by removing the bolt orpin 37, uponwhich the roller 36 is journaled, andreinserting said pin or bolt through its opening in the lever 38 and also through oneof the holes inthe lever 2i and appiying'a nut the lever 24 is then pivotally connected to the The outer end of pump-rod link 25, and as the pump-rod reeiprocates the motion thereof will be transmitted to the operating-pawl 22 by means of the lever connection 24 38.

Instead of arranging the mechanism of the regulator overhead the supporting-beam 9 for the regulator may be supported directly on the platform of the well, as shown in Fig. 6, and the draw-bar 16 may work up and down through an opening in said platform. Where the mechanism is located adjacent to the platform, a special wooden connecting-link 69 will be employed, connected at one end to the cam-operating lever and at the opposite end to the pump-rod 4 by means of an eyeplate or bracket 70, connected rigidly to the pump-rod, and a yoke 71, inserted through an opening in the eye-plate and having diverging terminal portions which are provided with a series of vertically-alined holes 72, adapted to receive the upper end of the link 69, the said link and yoke being connected by any suitable fastening devices. By providing the yoke with several sets of holes in the manner illustrated in Fig. 6 the link 69 and the mechanism of the regulator may be located at any desired distance from the pump-rod. The operation of the regulating mechanism will be precisely the same as that referred to in the description of Figs. 2 and 3.

The outer surface or end surface of the cam 31 is described on the arc of a circle the center of which is to one side of the fulcrum of the cam, so that the said outer surface of the cam is slightly eccentric, the curvature of the cam being such that after the roller 36 passes the rounded corner 73 of the cam and travels along the said outer or end surface 74 thereof the latter will act to slightly raise the roller, and thus when the movement of the cam is reversed the roller will travel with greater freedom backward toward the corner 73 of the cam until it again comes in contact with and travels along the main operative surface of the cam.

From the foregoing description it will be seen that I have provided simple and eliicient means whereby the motion of the pump-rod may be transmitted to the draw-bar or windmill connection, and at the same time provision is made for imparting a predetermined and limited amount of movement to the drawbar or windmill connection irrespective of the length of throw of the pump-rod. In this way the regulator is adapted to a variety of windmills and pump-rods having different lengths of stroke. It will also be seen that the regulator is controlled by a float which is in turn controlled by the water-level in the receiving tank or reservoir, whereby the desired level of water will be maintained in such reservoir. It will further be seen that the regulator may be readily converted from a cam-operating device into a straight-leveroperating device with slight change.

From the foregoing it is thought that the construction, operation, and many advan= tages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changesin the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
